The invention relates to an interfacing device for pseudo-differential transmission through interconnections used for sending a plurality of electrical signals. The interfacing device of the invention comprises signal terminals (101) and a common terminal (100) distinct from the reference terminal (ground). A transmitting circuit (5) receiving the "input signals of the transmitting circuit" coming from a source (2) delivers, when the transmitting circuit (5) is in the activated state, currents to the signal terminals (101). A receiving circuit (6) delivers, when the receiving circuit (6) is in the activated state, "output signals of the receiving circuit" determined each by the voltage between one of said signal terminals (101) and said common terminal (100), to the destination (3). A termination circuit (4) is such that, when it is in the activated state, it is approximately equivalent, for said signal terminals (101) and said common terminal (100), to a network consisting of 4 branches, each branch being connected to the common terminal (100) and to one of said signal terminals (101).
